Pirelli believe it is impossible to predict the way the tyres will behave in Montreal

It is impossible to predict the way the tyres will predict for the Canadian Grand Prix next weekend, according to Pirelli.

The Italian tyres company is taking its soft and super soft compounds to Montreal, where the circuit is a mixture of street and permanent road course.

Paul Hembery, the director of motorsport for the Italian tyres company, told AUTOSPORT: “Tyres are a strange thing. If they are too hard, and they don’t provide any grip, then they can wear much faster.

“The reason we are going super soft and soft is that you want to have grip from the tyre, if you go with something too hard then you end wheel-spinning, tyres grain and they get consumed even quicker. I know it is a strange conundrum and a lot of people are thinking Montreal will be very aggressive but probably not.

“We’ve never run there. I have a pretty good idea here, I have been to Montreal. I’ve seen the track, I’ve walked it, but I am not going to make a prediction. We want to see what happens in first practice.
